A 17-year-old motorcyclist was critically injured in a collision in Kuliouou Wednesday night.
The collision occurred at the intersection of Kalanianaole Highway and Kuliouou Road at about 11:45 p.m.
Police said a white 2015 Acura sport utility vehicle driven by a 30-year-old man was traveling eastbound on the highway and was making a left turn onto Kuliouou Road when a silver 2016 Yamaha motorcycle operated by the 17-year-old boy traveling westbound on the highway disregarded a red traffic signal and broadsided the passenger side of the SUV.
The motorcyclist who was wearing a helmet at the time was taken in critical condition to a hospital.
The 30-year-old Acura driver and his passenger, a 59-year-old woman, did not sustain any injuries.
Police said speed may be a factor on the part of the motorcyclist.
An investigation is ongoing.
